I recently got a new Sony STR-AN1000 receiver to replace my old Yamaha. I confirmed that the receiver was in the Harmony database.  So I updated the activities with the new receiver (I had to use the 2nd blaster) and everything works....mostly.

Usually, about 75% of the time, when switching from Cable to Roku the receiver shuts off. Then I think it turns back on when it sees a signal from the Roku.  Maybe 25% of the time it shuts off when going from Roku to Cable.

I confirmed that this is strictly a Harmony issue, because it works flawlessly with the Sony remote.

I am pretty sure that I found the problem. When switching inputs, Harmony sends an "on" command to the receiver. Because it's a toggle (not discrete) the receiver turns off.

So, where can I find discrete Sony power commands? I still have my Pronto 5000 for emergencies. I can convert the codes with prontohex, put them in the Pronto, then manually program them into the Harmony.

Sound correct?
